Weight centile crossing in infancy: correlations between successive months show evidence of growth feedback and an infant-child growth transition.

Despite the modest sizes of ±0.2 to 0.3—the variance explained rarely exceeded 10%—these extreme correlations were highly significant and the pattern with age was entirely consistent [correlations of ±0.15 (Widdowson) or ±0.25 (CIGS) were significant at P = 0.0001].
